Abstract

The application relates to a battery pack, which comprises a battery cell, a first shell, a second shell and a top cover. The second shell covers the first shell and forms a first accommodating cavity together, a battery cell is arranged in the first accommodating cavity, the top cover is arranged on one side, away from the first shell, of the second shell, a second accommodating cavity is formed between the top cover and the second shell, a first electric connecting piece is arranged in the second accommodating cavity, one end of the first electric connecting piece is connected with the battery cell, and the other end of the first electric connecting piece is used for externally connecting a wiring terminal. The battery pack is additionally provided with a top cover at the outer side of the second shell so as to accommodate the first electric connecting piece, so that the battery unit and the first electric connecting piece are independently installed in different spaces for installation. When the first electric connecting piece damages, the first electric connecting piece that directly damages can be changed, reduced impurity such as external dust and get into first holding chamber, produce the probability of harmful effects to the battery monomer, prolonged the life of battery package to the protective capability of battery package self has been improved.

Description

Battery pack Technical Field The application relates to the technical field of lithium batteries, in particular to a battery pack. Background With the popularization of new energy automobiles, energy storage power stations, consumer electronics and industrial equipment, battery packs are often exposed to outdoor moisture, rain and snow, and water or high humidity environments (e.g., electric automobile chassis, outdoor energy storage boxes, unmanned aerial vehicles, etc.). The risks of water vapor permeation, liquid soaking, etc. are significantly increased. Therefore, improving the protection performance of the battery pack is a problem that needs to be solved at present. Disclosure of utility model Based on this, it is necessary to provide a battery pack having an effect of improving the protection effect and prolonging the service life of the battery pack, aiming at the problem that the protection effect of the battery pack is poor. A battery pack, comprising: A battery cell; A first housing; the second shell covers the first shell and forms a first accommodating cavity together, and the battery cells are arranged in the first accommodating cavity; The top cap is located the second casing deviates from one side of first casing, the top cap with form the second between the second casing and hold the chamber, the second holds the intracavity and is equipped with first electric connection spare, the one end of first electric connection spare with battery cell is connected, and the other end is used for external binding post. In one embodiment, the battery pack further includes a second electrical connector, a portion of the second electrical connector is located in the first accommodating cavity and connected with the battery unit, and another portion of the second electrical connector penetrates through the second housing and is detachably connected with the first electrical connector. In one embodiment, the second electrical connector comprises an electrically connected body and a connecting piece, the body is located in the first accommodating cavity and connected with the battery unit, and the connecting piece penetrates through the second shell and is detachably connected with the first electrical connector. In one embodiment, the second housing is provided with a slot, the slot is penetrated by the connecting piece, a sealing element is arranged around the slot, and the sealing element is positioned between the second housing and the first electrical connecting piece. In one embodiment, the seal is configured as a ring, the number of slots being plural, and the orthographic projection of all the slots onto the second housing falling within the seal. In one embodiment, the first electrical connector includes a board body and a terminal, the board body is provided with a clamping groove, the clamping groove is communicated with the slot, the connecting piece is clamped, and the terminal is used for externally connecting the wiring terminal. In one embodiment, the top cover is provided with an opening, and the opening communicates the second accommodating cavity with the outside and is arranged opposite to the terminal.
